To find whether a string has all the same characters. Traverse the whole string from index 1 and check whether that character matches the first character of the string or not. If yes, then match until string size. If no, then break the loop.
Python strings equality can be checked using == operator or __eq__() function. Python strings are case sensitive, so these equality check methods are also case sensitive.
String rmtdir = Filename. substring(Filename. length() - 12, Filename. length() - 14);
You can use string. indexOf('a') . If the char a is present in string : it returns the the index of the first occurrence of the character in the character sequence represented by this object, or -1 if the character does not occur.
Lets say I have:
str = "Hello! My name is Barney!"
Is there a one or two line method to check if this string contains two !?
